Description

Technical Field

[0001] This utility model belongs to the technical field of coal conveying equipment, and in particular relates to a coal conveying device. Background Technology

[0002] Currently, coal transportation requires conveying devices, some of which are belt conveyors. The distance a belt conveyor can transport coal depends on its length; therefore, belt conveyors with longer transport distances are relatively long. Furthermore, in existing technologies, transporting long belt conveyors is sometimes inconvenient due to the non-adjustable length of these conveyors. Thus, existing technologies still have shortcomings and deficiencies. Utility Model Content

[0003] The purpose of this invention is to provide a coal conveying device to solve the problems mentioned in the background art.

[0004] The technical solution adopted by this utility model to solve the above problems is as follows: A coal conveying device includes a horizontally arranged belt conveyor with a frame. The feed end of the belt conveyor is supported by a support structure connected to the frame. A U-shaped support with an upward-facing U-shaped opening is rotatably connected to the support structure via vertically distributed rotating shafts. A screw conveyor is mounted on the U-shaped support. The screw conveyor includes a housing parallel to and above the belt conveyor. The housing is located inside the U-shaped support and rotatably connected to it. A screw conveying shaft coaxial with the housing is rotatably connected inside the housing. One end of the screw conveying shaft is driven by a drive motor. Both ends of the housing are located outside the belt conveyor. A feed hopper is fixedly connected to the top of one end of the housing. A vertically distributed support leg assembly is installed at the end of the housing where the feed hopper is installed and located outside the discharge end of the belt conveyor. A discharge port is opened at the bottom of the end of the housing away from the support leg assembly. The discharge port is located outside the feed end of the belt conveyor.

[0005] Furthermore, the bottom of the housing is vertically provided with a number of filter holes that are equidistantly distributed along the length of the housing.

[0006] Furthermore, the support structure is equipped with a horizontally distributed annular structure. An annular groove is formed on the inner wall of the annular structure, and a disc is rotatably connected to the annular structure through the annular groove. The rotating shaft is coaxial with the disc, and the bottom end of the rotating shaft is connected to the disc. The top end of the rotating shaft passes through the annular structure and is connected to the U-shaped support.

[0007] Furthermore, the outrigger assembly includes vertically distributed sleeves, with a support rod slidably connected inside the sleeves. A locking bolt capable of locking the position of the support rod is installed between the top of the sleeve and the support rod. The top end of the support rod is located outside the sleeve and hinged to the housing.

[0008] Furthermore, horizontally distributed support shafts are fixedly connected to both sides of the housing. The support shafts are located at the end of the housing near the support leg assembly. Supports mounted on the frame are provided on both sides of the conveying direction of the belt conveyor. The support is positioned opposite to the support shaft, and a groove is provided on the top surface of the support to accommodate the support shaft.

[0009] The beneficial effects of this utility model by adopting the above technical solution are as follows: In use, the screw conveyor casing and the U-shaped support are rotatably connected, allowing the screw conveyor to rotate vertically. After raising the end of the screw conveyor where the feed hopper is installed, the U-shaped support is rotatably connected to the support structure via vertically distributed shafts, allowing the screw conveyor to rotate horizontally until the discharge port on the screw conveyor is located inside the support structure. Then, the end of the screw conveyor where the feed hopper is installed can be lowered, and the support leg assembly supports the screw conveyor. At this point, the screw conveyor can first transport coal, and then the belt conveyor can transport coal, effectively extending the length of the conveying device to ensure long-distance coal transport. Furthermore, when transporting the conveying device, the screw conveyor can be rotated in the opposite direction until it is located outside the support structure, shortening the length of the conveying device and facilitating transport.

[0012] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0013] like Figures 1 to 6 As shown, this utility model provides a coal conveying device, including a horizontally arranged belt conveyor 2 with a frame 21. Specifically, the belt conveyor 2 is a conventional belt conveyor used for conveying coal. The belt conveyor 2 also includes conveyor rollers, a conveyor belt, a conveyor motor 22, and support legs 23, etc. The conveyor motor 22 is externally connected to a power supply and a start / stop switch. The feed end of the belt conveyor 2 is equipped with a support structure 1 connected to the frame 21. Specifically, the support structure 1 is an inverted U-shaped support. Figure 1 For example, the side of the support structure 1 closest to the support 9 is the inner side of the support structure 1; a U-shaped support 5 with an upward-facing U-shaped opening is rotatably connected to the support structure 1 via vertically distributed rotating shafts 4. A screw conveyor 3 is installed on the U-shaped support 5. The screw conveyor 3 includes a housing 31 that is parallel to and above the belt conveyor 2. The housing 31 is located inside the U-shaped support 5 and is rotatably connected to the U-shaped support 5 via horizontally arranged fixed shafts 32. Specifically, there are two fixed shafts 32, which are symmetrically distributed on the housing. Both sides of the housing 31, and one end of the fixed shaft 32 is fixedly connected to the outer wall of the housing 31, and the other end of the fixed shaft 32 is rotatably connected to the U-shaped bracket 5; a spiral conveying shaft 33 is rotatably connected inside the housing 31 and is coaxially arranged with the housing 31. One end of the spiral conveying shaft 33 is connected to a drive motor 34. The drive motor 34 is externally connected to a power supply 38 and a start / stop switch installed on the outer wall of the housing 31. When in use, when the drive motor 34 is started, it can drive the spiral conveying shaft 33 to rotate in order to convey coal inside the housing 31.

[0014] In addition, both ends of the housing 31 are located outside the belt conveyor 2. The top of one end of the housing 31 is fixedly connected to the feed hopper 6, through which coal can be added into the housing 31. The end of the housing 31 where the feed hopper 6 is installed is equipped with vertically distributed support leg assembly 7 located outside the discharge end of the belt conveyor 2. The bottom of the end of the housing 31 away from the support leg assembly 7 is provided with a discharge port 35, which is located outside the feed end of the belt conveyor 2.

[0015] Specifically, during use, since the casing 31 of the screw conveyor 3 is rotatably connected to the U-shaped support 5, the screw conveyor 3 can be rotated vertically. After raising one end of the screw conveyor 3 where the feed hopper 6 is installed, the U-shaped support 5 is also rotatably connected to the support structure 1 via vertically distributed rotating shafts 4, allowing the screw conveyor 3 to rotate horizontally until... Figure 5 As shown, when the discharge port 35 of the screw conveyor 3 is located inside the support structure 1, one end of the screw conveyor 3 with the feed hopper 6 installed can be lowered, and the screw conveyor 3 is supported by the support leg assembly 7. At this time, the screw conveyor 3 can first transport the coal, and then the belt conveyor 2 can transport the coal. This is equivalent to extending the length of the conveying device to ensure that the conveying device can transport coal over long distances. On this basis, when the conveying device needs to transport, after raising one end of the screw conveyor 3 with the feed hopper 6 installed, the screw conveyor 3 is rotated in the reverse direction until it is as shown. Figure 1 As shown, when the discharge port 35 on the screw conveyor 3 is located outside the support structure 1, one end of the screw conveyor 3 that is installed in the feed hopper 6 can be lowered, and the screw conveyor 3 is supported by the support leg assembly 7, so that the screw conveyor 3 is mounted above the belt conveyor 2. At this time, the length of the conveying device can be shortened, which makes it easier to transport the conveying device.

[0016] Furthermore, such as Figure 4 As shown, the bottom of the housing 31 has several filter holes 36 that are equidistantly distributed along the length of the housing 31. Specifically, during use, when the screw conveyor 3 is used to transport coal, small pieces of coal can be filtered out through the filter holes 36. This reduces the number of small pieces of coal falling into the belt conveyor 2, thereby reducing the number of times the belt conveyor 2 gets stuck and damaged.

[0017] The specific arrangement of the U-shaped bracket 5 being rotatably connected to the bracket structure 1 via the rotating shaft 4 is as follows: (e.g.) Figures 1 to 3As shown, a horizontally distributed annular structure 8 is installed on the support structure 1. An annular groove 81 is provided on the inner wall of the annular structure 8, and a disc 10 is rotatably connected to the annular structure 8 through the annular groove 81. The rotating shaft 4 is coaxially arranged with the disc 10, and the bottom end of the rotating shaft 4 is connected to the disc 10. The top end of the rotating shaft 4 passes through the annular structure 8 and is connected to the U-shaped support 5. This allows the U-shaped support 5 to be rotatably connected to the support structure 1, so that the screw conveyor 3 can rotate in the horizontal direction.

[0018] The specific setup method for outrigger assembly 7 is as follows: Figure 1 , Figure 5 and Figure 6 As shown, the support leg assembly 7 includes a vertically distributed sleeve 71. A support rod 72 is slidably connected inside the sleeve 71, and a locking bolt 73 is installed between the top of the sleeve 71 and the support rod 72 to lock the position of the support rod 72. The top of the support rod 72 is located outside the sleeve 71 and hinged to the housing 31. Specifically, the locking bolt 73 is threaded to the sleeve 71 and passes through the sleeve 71 radially. The head of the locking bolt 73 is located outside the sleeve 71. In use, by rotating the locking bolt 73 until the threaded end of the locking bolt 73 is pressed against the support rod 72, the relative position between the support rod 72 and the sleeve 71 can be fixed. By rotating the locking bolt 73 in the opposite direction until the threaded end of the locking bolt 73 is away from the support rod 72, the support rod 72 can slide along the sleeve 71. Since the top of the support rod 72 is hinged to the housing 31, the height position of the support rod 72 can be adjusted as follows: Figure 6 As shown, the tilt angle of the screw conveyor 3 can be adjusted to facilitate material feeding; in addition, the number of support leg assemblies 7 can be set to two sets, with the two sets of support leg assemblies 7 symmetrically distributed on both sides of the housing 31.

[0019] Furthermore, such as Figure 1 , Figure 5 and Figure 6 As shown, horizontally distributed support shafts 37 are fixedly connected to both sides of the housing 31. The support shafts 37 are located at the end of the housing 31 closest to the support leg assembly 7. Supports 9 mounted on the frame 21 are provided on both sides of the belt conveyor 2 in the conveying direction. The supports 9 are positioned opposite to the support shafts 37, and a groove 91 is provided on the top surface of the support 9 to accommodate the support shafts 37. Specifically, the groove 91 horizontally penetrates the support 9, and the axial line of the groove 91 is parallel to the support shaft 37. During use, when the position between the screw conveyor 3 and the belt conveyor 2 changes from... Figure 6 The transformation shown is as follows Figure 1As shown, the support leg assembly 7 can be rotated outward first, and then the screw conveyor 3 can be rotated until the screw conveyor 3 is rotated into place. Then the support shaft 37 can be placed on the support 9 through the groove 91, and the support 9 can directly support the screw conveyor 3. This makes it easier to adjust the length of the support leg assembly 7 later. Alternatively, after the support leg assembly 7 is adjusted to a suitable length, the support leg assembly 7 and the support 9 can jointly support the screw conveyor 3.
